GLASS-BEVELNG MACHNE.

To all whom it 'may concern:

Be it known. that l, Jenn H. STICH, a citizen of the United States, and resident of Davenport, Scott county, Iowa, have invented certain new and useful improve# .ments in Glass-Beveling Machines; and do hereby declare the following is a full, clear, and exactdescription of the same.I

My invention has relation to' improvements in machines for beveling plate glass; and it consists in the novel arrangement and eombinationo parts more fully set forth in the specification and pointed out in the claims.

ln the drawings Figure 1 is a vfront elevation. 2 is an end elevation. Fig. 3 is a vertical section on line 3-3 of Fig. l. Fig. l is a horizontal section along the line 1 of Fig. l. Fig. 5 is a vertical transverse section of the grinding disk mechanism alcngthe line 5 5 of Fig. 1. 6 is a detail of the clutch and driving gear.

Thefobject of my invention is to construct a plate glass beveling machinewby which plates of any dimensions can he readily handled, one in which the plate will be firmly supported at all points of its sur- :tace during the beveling'operation one by which the plate may be kept in contact with the grinding disk and in which the angle of bevel can he quickly adjusted and one having ther advantages to be hereinafter more fully described and particularly pointed out in the claims.

Referring to the drawings l represents a alta-ble base 2 the platen supported by the carriage 2g, 3 the motor mounted on the carriage, l the lateral. terminal supporting standards, 5 a central supporting standard, 6 a guide block pivotally supported by the central standard and one terminal standard, ji' the grinding disk'support, 8 and 9 bevel gear for actuation of disk mechanism, i() ahollow shaft. loosely mounted in the guide block and supported by shoulder 10-, and

V,supperting the grinding disk mechanism, il

a shaft actnatingthe bevel gear 8, l2 a gear ctuating the yshaft and meshing the gear .13 on the mot-or, 14 a shaft driven directly hy the notor and rotatably supportedby'the terminal standard 4, l5 a bevel. gear. rigid with shaft 14: and meshing with gear 1G, a"

sleeve 17 supported by the platen inclosing a shaft 18 integral with the bei'eled wheel 1G, a beveledV gear wheel 19 also integralA with shaft 1S, and meshing with wheels 2O Specification of Letters latent. Pgmbqt 16:36, 53-,

claim l. ln a machine for heveling glass a'4 platena motor mounted on Ythe platen a" shaft driven by the motor, a second. shaft- Sei'ial No.

and 2i a shaft integral with gears 20 and 2l rotatably supported by the yoke 23 attached to the platen a pinion rigid with the shaft- 2 andnieshing with rack 25, a reciprocating lever 2S pivotally supported oy the yoke at 27 operating clutch 26a, adapted to alternate engagement with wheels and 21 a traine :28 moving in guides 2S) attached `to the base an adjusting screw, 31 in the base and attached to the 'frame at 32 a crank 33 adapted to operate the adjusting` screw, inclines 35i at opposite ends of the frame.

The platen is mounted on rollers 35 ineving on ways 36 supported hy the table, an adjusting screw 3T is rotatably supported by the. bearing 38 rigidly attached to the table and actuates the platen laterally through the bearing 39. Rollers All) support the table on the hase and roll in ways Lil. Bolts 42 yieldably secure the rinding` disk to the 'disk support by means ot spiral springs lla, a -hlock i5 provided with conical apertures 46 and '7 terminates the hollow opening in the shaft. Bolts 48 rigidlyfsecure the disk support to the bevel gear, an extension 49,' is trunnioned in the standard l 'and upon the extension is mounted the worm. gear 50 actu# ated by the worm :31. fin auxiliary table 52 supports the glass 5?; to be beveled. A support 5i rigid with the hose .supports the rack. T he zgjlass plate to be beveled is laid upon table 52 and the mechanism started. Sand and water or other inding material is introduced within the hollow shagt l() from a hopper not shown in the drawing, the table is adjusted to near the proper position hy the screw 31 and the crank 33. The grinding disk is adjusted to the proper bevel hy the worm 5l. lhe platen is adgrinding'disk and the 'reciprocating motion of the carriage is maintained during the ,operation or grinding.

Havi hus described my'invention what vjusted to the exact position by the screw 38 -and the crank 38a.

llG

geared to the motor, standards on the platen a grinding disk a block rotatably supportlng the disk and trunnioned in the stand arde, a gear attached to one of the trun nions, a Worin opel-ating the gear, a table supporting the glass to be operated upon, a table supporting the platen, a frame vsupporting the table means for reciprocating the table longitudinally on the frame.

2. ln a lraehine for beveling glass a suitable sand feeding Wheel, a hollow spindle integral with the Wheel, a block Within the spindle adjacent to the grinding disk oppositely disposed concentric del'nessions in the block meeting to form a small aperture in the block midway of its thickness, and means for supporting the Work in operative relation to the grinder.
